Oct 13 04:17:10 <veremit> jkridner: random question .. but do you know anything about when the arduino tre is due to come out?
Oct 13 04:17:26 <veremit> since I see your name mentioned on their pages :P
Oct 13 04:18:26 <veremit> along with gerald's.
Oct 13 08:40:49 <guest___> hi, can i use a 7.5v dc to supply the beaglebone black? what are the range?
Oct 13 08:55:55 <woglinde> guest___ read the trm?
Oct 13 09:17:53 <purna> hello
Oct 13 09:18:43 <purna> is there any evaluation board which supports 8 channel pwm channel
Oct 13 09:21:18 <purna> hiii
Oct 13 09:21:52 <mashiara> Nucleo ?
Oct 13 09:22:08 <purna> hi
Oct 13 09:22:25 <mashiara> of course depending on your exact needs bit-banging the PWM is probably possible
Oct 13 09:23:05 <av500> or PRUing it
Oct 13 09:23:18 <mashiara> oh yeah, BBB has the PRU...
Oct 13 09:23:28 * mashiara always forgets
Oct 13 09:23:38 <woglinde> I am right now learing all about the PRU
Oct 13 09:23:47 <woglinde> learning
Oct 13 10:43:22 <tasslehoff> is it the mem= in bootargs that should give me memory to do dma_alloc_coherent from?
Oct 13 10:49:40 <tasslehoff> or rather, where does dma_alloc_coherent try to get memory from?
Oct 13 10:53:20 <av500> from that
Oct 13 11:02:09 <tasslehoff> so if I have no mem= in my bootargs, there is no wonder that allocation fails :)
Oct 13 11:02:35 <woglinde> yes
Oct 13 11:14:39 <tasslehoff> anything wrong with this cmdline: http://pastebin.com/u98QsK4E ?
Oct 13 11:33:55 <tasslehoff> don't answer...
Oct 13 11:34:20 <av500> 1M?
Oct 13 11:34:22 <av500> that much???
Oct 13 11:34:30 <av500> 640k is enough for everybody!
Oct 13 11:34:49 <ogra_> !
Oct 13 11:35:09 <av500> tasslehoff: if you dont have mem= in your command line, it could still be defined in a board file
Oct 13 11:35:12 <av500> or via DT
Oct 13 11:36:37 <woglinde> hm I will see the panto DT talk later
Oct 13 11:38:07 <tasslehoff> av500: ok. mem=256M lets it boot again, but my alloc still fails, so that was not it
Oct 13 11:40:43 <av500> fails how?
Oct 13 11:44:16 <tasslehoff> dma_alloc_coherent returns a null ptr
Oct 13 11:44:47 <av500> for what size alloc?
Oct 13 11:47:01 <tasslehoff> 1024 bytes
Oct 13 11:47:16 <av500> oh
Oct 13 11:51:26 <woglinde> is nt that to small?
Oct 13 11:58:36 <tasslehoff> woglinde: tried 4096 and 8192, but it failed then as well.
Oct 13 12:30:34 <cityoflights2> did anyone try to use a pcb antena on a cape which is air coupoled to a wifi usb adaptor?
Oct 13 13:39:07 <somazero> Greetings!  I see some lpae kernels in the repo.  I'm unfamiliar with these, and I was wondering if anyone could provide a couple words on benefit/use.  I appreciate it!
Oct 13 13:44:17 <av500> what repo?
Oct 13 13:45:17 <somazero> Ahh, yes, sorry - debian, rcn-ee
Oct 13 13:45:49 <somazero> Just curious...I'm googling, of course.  I'm wondering if it's security related.
Oct 13 14:40:40 <mistawright> hi guys has anyone used pololu's dual motor driver the tb6612fng with the beaglebone black? I had an issue where I was not able to get it to reverse using the beaglebone black. I tested it with an arduino nano and then when i attempted to use it with the beaglebone again it burned up. I may also be at the upper limit of what it can take voltage wise as I am using a 3s lipo that seems to be putting out 12v+
Oct 13 15:34:27 <Thomas__> Hi! Does anybody know a tutorial for loading a custom pin configuration (DTO) for the BBB directly from an external EEPROM (on a cape board)?
Oct 13 15:36:13 <amila> hi, is there a way to monitor all the events of BBB and draw a graph using nodejs? Or any other ways to making the requirement a success?
Oct 13 15:40:40 <rwr> amila, yes.
Oct 13 15:42:42 <amila> rwr: can you please give me more detail please?
Oct 13 15:58:59 <mashiara> Firts figure out how to do those graphs
Oct 13 16:00:23 <mashiara> Then you need to think about what your "events" are
Oct 13 16:01:22 <mashiara> I would propably make a separate process for logging the events and another for displaying those graphs
Oct 13 16:02:07 <mashiara> Sqlite is pretty handy as long as you do not need concurrent writes
Oct 13 16:02:12 <rwr> I have a much better, and easier, method
Oct 13 16:03:09 <rwr> 1. find and paste some random code from the Internet
Oct 13 16:03:12 <rwr> 2. ???
Oct 13 16:03:15 <rwr> 3. profit!
Oct 13 16:03:20 <thurgood> lol
Oct 13 16:03:30 <thurgood> nice soth park reference
Oct 13 16:03:33 <thurgood> south even
Oct 13 16:05:13 <mashiara> Should "we're not here to do your homewrok for you" be the first thing in the topic?
Oct 13 16:25:12 <thurgood> at the uni I went to the teachers would have found the students coming here with exact steps questions and flayed them... not saying that's good or proper, just how it was
Oct 13 16:50:33 <jens___> Hi, I am trying to find the git repository that was used to build the 3.17.0-bone4 kernel.
Oct 13 17:58:08 <dancinglucifer> hey guys. just bought my first beaglebone and plugged it into my computer but my computer is not seeing it. help?
Oct 13 17:58:57 <mashiara> which operating system ?
Oct 13 17:59:13 <dancinglucifer> i am using windows 7
Oct 13 18:00:11 <mashiara> and you have installed the drivers ? http://beagleboard.org/getting-started#step2
Oct 13 18:00:30 <mashiara> you have read all of  that page, right ?
Oct 13 18:00:42 <mashiara> if not, start with that...
Oct 13 18:00:52 <dancinglucifer> thats not my problem
Oct 13 18:01:12 <dancinglucifer> my problem is getting my computer to see the beaglebone so i can install the drivers
Oct 13 18:01:41 <mashiara> have you tried an external power supply ?
Oct 13 18:01:59 <dancinglucifer> i am plugging in the external one as we speak
Oct 13 18:01:59 <rwr> have you tried turning it off and on again?
Oct 13 18:02:09 <mashiara> is this BeagleBone or BeagleBone black  btw...
Oct 13 18:02:46 <dancinglucifer> beaglebone the older one
Oct 13 18:03:39 <dancinglucifer> when i plug it in am i supposed to get any lights other than the steady blue power light?
Oct 13 18:04:15 <mashiara> and you have SD-card with a working linux image on it inserted ?
Oct 13 18:04:35 <dancinglucifer> i have a sd card but its blank
Oct 13 18:04:57 <mashiara> then there is nothing to boot from, black has the onboard eMMC
Oct 13 18:05:11 <dancinglucifer> oh okay
Oct 13 18:05:37 <mashiara> so start by putting an image on the SD card so the board can boot
Oct 13 18:06:02 <mashiara> http://www.elinux.org/Beagleboard:BeagleBone#Image_Files
Oct 13 18:06:35 <dancinglucifer> you guys are awesome btw
Oct 13 18:08:37 <mashiara> only when we're not asked to do someones homework for them...
Oct 13 18:09:26 <dancinglucifer> lol havent had to do hw for a long time now
Oct 13 18:09:31 <dancinglucifer> thank god
Oct 13 18:12:08 <dancinglucifer> i am going to be using my beagle as a plex server. which image do you guys recommend?
Oct 13 18:14:02 <mashiara> I would probably try to find some Ubuntu based image but I'm weird in that way...
Oct 13 18:14:10 <mashiara> Debian is the second choice
Oct 13 18:14:28 <dancinglucifer> never heard of debian i will look that one up
Oct 13 18:15:31 <dancinglucifer> oh and before i forget i have a 7in touch screen i will want to use with it too
Oct 13 18:15:52 <mashiara> that might get interesting... what kind of interfaces does the screen have ?
Oct 13 18:16:10 <dancinglucifer> serial i think
Oct 13 18:16:17 <dancinglucifer> it only works with the bone
Oct 13 18:16:20 <mashiara> and for video ?
Oct 13 18:16:25 <dancinglucifer> yup
Oct 13 18:16:53 <dancinglucifer> i am looking at it now to see if i can get any info so you can look it up
Oct 13 18:18:43 <dancinglucifer> BB view LCD Expansion Cape for beaglebone family is all i see on it
Oct 13 18:19:26 <mashiara> this one http://www.element14.com/community/docs/DOC-55844/l/expansion-board-for-beaglebone-family-with-7-inch-lcd ?
Oct 13 18:21:04 <dancinglucifer> yeah looks like that
Oct 13 18:21:21 <mashiara> you might want to start with the precompiled Image they mention
Oct 13 18:22:45 <mashiara> because otherwise you will need to learn how to compile kernel modules to get the drivers working on some other image.
Oct 13 18:23:24 <dancinglucifer> okay i am looking for the precompiled image
Oct 13 18:24:32 <mashiara> http://www.element14.com/community/docs/DOC-67958?ICID=BBB-feature-viewpanel
Oct 13 18:25:01 <|PiP|`> Can anyone please provide me the link to the Beaglebone flasher that works from linux? the sdcard on my BBB is damaged and i need way to flash the device directly.
Oct 13 18:26:20 <mashiara> dancinglucifer, yay they have Debian image too. Go with that...
Oct 13 18:26:28 <dancinglucifer> thanks mashiara
Oct 13 18:26:34 <dancinglucifer> i just downloaded it
Oct 13 18:26:49 <mashiara> they made that page pretty hard to find for some reason
Oct 13 18:27:17 <mashiara> the link in the datasheet went to some generic BeagleBone page and I had to search that page for the downloads section...
Oct 13 18:27:39 <dancinglucifer> i repeat your awesome
Oct 13 18:27:54 <mashiara> actually that might be BBB image :(
Oct 13 18:28:43 <mashiara> try it anyway, if it doesn't work you will need to dig around http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone for an older one
Oct 13 18:32:20 <mashiara> PIP: BBB has no JTAG over USB, you're going to need a proper JTAG tool to flash the eMMC if you cannot boot the board either from eMMC or SD
Oct 13 18:32:46 <mashiara> http://elinux.org/Beagleboard:BeagleBoneBlack#Optional_JTAG
Oct 13 18:59:51 <vvu> |PiP|`: https://github.com/ungureanuvladvictor/bbblfs
Oct 13 18:59:57 <vvu> this is the one you are looking, i presume :)
Oct 13 19:00:14 <vvu> it allows to flash the emmc over usb
Oct 13 19:09:02 <mashiara> ah, it can boot over USB, handy...
Oct 13 19:09:15 <mashiara> it seems I’m old fashioned...
Oct 13 19:09:32 <vvu> mashiara: :)
Oct 13 20:21:25 <beagler01> anyone know how to limit memory available to the kernel on the beaglebone black?
Oct 13 20:21:51 <beagler01> tried mem=LIMIT in uEnv.txt. that didn't work
Oct 13 20:22:53 <beagler01> noticed the memory node in the device tree blob. Currently showing 256 MB; however, /proc/meminfo show 512 M available - so that doesn't appear to work either
Oct 13 20:23:09 <beagler01> anyone?
Oct 13 20:23:36 <agmlego> SUch patience.
Oct 13 20:23:38 <agmlego> Much ask.
Oct 13 20:23:40 <agmlego> Very wait.
Oct 13 20:23:44 <agmlego> Wow, amaze.
Oct 13 20:27:03 <tasslehoff> Anyone else had issues with dma_alloc_coherent failing? omap3@2.6.39.
Oct 13 20:28:10 <tasslehoff> alloc_page did not fail, but I somehow mess it up when I use the page I was graciously given
Oct 13 22:29:46 <PGBeagle> I am trying to backup all of my "User" information from my BBB to my Mac.  By searching Google I have fould that I can open a terminal on my Mac...
Oct 13 22:30:16 <PGBeagle> and change to the directory I want to save to.  Then "sftp" into the BBB and use "get" to grab a file...
Oct 13 22:30:32 <PGBeagle> and it will be transferred to the proper directory on the Mac.
Oct 13 22:31:05 <PGBeagle> However,  I want to be able to transfer directories with their contents and sub-directories with their contents.
Oct 13 22:31:40 <PGBeagle> I get the error message: "Cannot download non-regular file".  Is there another command, or option?
Oct 13 22:31:42 <thurgood> I think -R is the recursive flag for sftp... easy enough to check
Oct 13 22:32:39 <PGBeagle> Also, when logged in as "sftp" what is the command for "get --help"?  (That doesn't work)
Oct 13 22:33:18 <thurgood> you actually want scp as the command
Oct 13 22:33:30 <thurgood> sftp is a protocol
Oct 13 22:33:48 <PGBeagle> "get -R tmp" worked!
Oct 13 22:33:49 <agmlego> Or rsync.
Oct 13 22:33:56 <agmlego> rsync > scp.
Oct 13 22:35:08 <thurgood> rsync is cool but requires setup
Oct 13 22:35:20 <agmlego> Not that much.
Oct 13 22:35:35 <agmlego> It basically just has to be installed at all.
Oct 13 22:41:05 <PGBeagle> When I logged into the BBB I used "sftp root@beaglebone.local" and it gave me a "sftp>" prompt.  From there the "get" worked.
Oct 13 22:41:23 <djlewis> later . . .
Oct 13 22:44:15 <agmlego> PGBeagle: sftp works, but there are better, easier methods.
Oct 13 23:37:16 <chakoalha_> hey guys
Oct 13 23:40:15 <chakoalha_> I've been testing pwm with python bib and i noticed that the LED flashes before starting the pwm. Is it normal? How can I take away this?
